This Split-type air conditioner uses the new HFC refrigerant (R410A) that does not harm the ozone layer. The operating pressure of the new refrigerant R410A is 1.6 times higher than that of the conventional refrigerant (R22). The refrigerant oil is also changed
according to the refrigerant exchange. Therefore, ensure that water, dust does not come into contact with existing refrigerant or refrigerant oil in the installation or maintenance cycle.
